I want to add much HTML to my form elements in order to arrange them on the page, I will be using bootstrap framework to do this.
Which method would be better, to create a twig template file or to use HOOK_form_alter?
If the way to do this would be to create a twig template file, then how can I ensure the form html tags with the form method is also rendered to the page? I have attempted to do this but I don't know how to get the actual form to render, just the inputs are there in the html source code.
I know in Drupal 7 that you had to render something called child elements, but when I check for this array in Kint there is no such thing.
